摘　　要：基于“反应分子与活性相最优匹配(ROCKET)”制备技术平台开发了高活性、高稳定性的柴油超深度加氢脱硫催化剂RS-2100(NiMo)和RS-2200(CoMo)。根据不同催化剂的反应性能特点,结合加氢反应器内不同位置的条件因素,开发了柴油加氢催化剂级配技术。通过两种催化剂的组合,获得脱硫活性及稳定性较高且化学反应氢耗降低的催化剂级配体系。与单一催化剂相比,采用优化的催化剂级配技术可以使相对脱硫活性提高12%;在实现超深度脱硫的同时,反应化学氢耗降低15%左右。工业应用结果表明,采用优化的催化剂级配技术,可以在装置负荷较设计提高25%的前提下,实现超低硫柴油的生产。The highly active RS-2100(NiMo)and RS-2200(CoMo)catalysts for ultra-deep hydrodesulfurization of diesel fuel were developed based on the preparation technology platform of"Reactant-active phase Optimization&Cost-effective Key Technology(ROCKET)".According to the reaction characteristics of different catalysts and the conditions of different positions in the hydrogenation reactor,the gradation technology of diesel hydrogenation catalysts was developed.Through the combination of the two catalysts,a catalyst system with higher desulfurization activity and stability and lower hydrogen consumption for chemical reaction was obtained.Compared with the single catalyst system,the relative desulfurization activity can be increased by 12%by using the optimized catalyst gradation technology.At the same time,the reaction chemical hydrogen consumption is reduced by about 15%.The industrial application results show that the production of ultra-low sulfur diesel oil can be realized under the premise that the load of the plant can be increased by 25%compared with the design by using the optimized catalyst gradation technology.
